Figure 7. Model of epidermal lineage progression in planarian.

Figure 7

(A) Schematic of ultrastructures of epidermal precursor and mature epidermal cell. Epidermal precursors contain features of the mature epidermal cells including large rod-shape rhabdites and small oval-shape granules. They are also abundant in mitochondria. (B) Schematic of the planarian epidermal lineage progression and the phenotypic differences in p53-, zfp-1-, soxP-3 and pax-2/5/8 (RNAi) animals. (C) Proposed transcription network in the epidermal lineage progression. Gray arrow represents aspects of the network not studied in depth.
